ABSTRACT

OBJECTIVE To analyze the etiological characteristics and risk factors of burn wound infection to provide scientific basis for preventive measures. METHODS The pathogens and risk factors of wound infection of burn patients were investigated. RESULTS Among 341 burn patients form Jan 2005 to Dec 2007, 257 patients were cultured positively in their wound surface with the total infection rate 86.0%. In the early period of infection, Gram-positive cocci were the main pathogens in preinfection, then Gram-negtive bacilli and fungal infection increased. Most of pathogens were opportunistic. From d4 to d10 after burn was the dangerous period of infection. Infection rate was related to the sizes of burn area. CONCLUSIONS Visiting hospital, debridement and takeing specimens to culture in time, correct antibiotics treatment, sterile environment and aseptic operation are the effective measures to reduce the wound infection.
